Access Network Selection for a Ue Not Supporting Nas Over Non-3gpp Access

3. The apparatus of claim 2, wherein determining the set of PLMNs which are connectable using a 5G connectivity without comprises using an access network query protocol (“ANQP”) to acquire a list of PLMNs connectable via each available non-3GPP access network using a 5G connectivity without.

4. The apparatus of claim 2, wherein the first non-3GPP access network is a highest priority available non-3GPP access network that supports connectivity to the first PLMN.

5. The apparatus of claim 1, wherein beginning the connectivity procedure over the first non-3GPP access network comprises sending a request message to the first non-3GPP access network comprising a network access identifier (“NAI”), the NAI containing an identifier for the first PLMN.

6. The apparatus of claim 5, wherein the NAI contains also an identifier for a first Single Network Slice Selection Assistance Information (“S-NSSAI”) and wherein the connectivity procedure creates a data connection for the apparatus via the first S-NSSAI in the first PLMN.

8. The apparatus of claim 7, wherein the second list is ordered based on operating parameters of the plurality of available non-3GPP access networks.

9. The apparatus of claim 1, wherein beginning the connectivity procedure comprises creating a data connection via the first PLMN and via one of: a trusted wireless local area network interworking function (“TWIF”) in the first non-3GPP access network, and a fixed network residential gateway (“FN-RG”) in the first non-3GPP access network.

12. The method of claim 11, wherein determining the set of PLMNs which are connectable using a 5G connectivity without NAS comprises using an access network query protocol (“ANQP”) to acquire a list of PLMNs connectable via each available non-3GPP access network using a 5G connectivity without NAS.

13. The method of claim 11, wherein the first non-3GPP access network is a highest priority available non-3GPP access network that supports connectivity to the first PLMN.

14. The method of claim 10, wherein beginning the connectivity procedure over the first non-3GPP access network comprises sending a request message to the first non-3GPP access network comprising a network access identifier (“NAI”), the NAI containing an identifier for the first PLMN.

15. The method of claim 14, wherein the NAI contains also an identifier for a first Single Network Slice Selection Assistance Information (“S-NSSAI”) and wherein the connectivity procedure creates a data connection for the apparatus via the first S-NSSAI in the first PLMN.

17. The method of claim 16, wherein the second list is ordered based on operating parameters of the plurality of available non-3GPP access networks.

18. The method of claim 10, wherein beginning the connectivity procedure comprises creating a data connection via the first PLMN via one of: a trusted wireless local area network interworking function (“TWIF”) in the first non-3GPP access network, and a fixed network residential gateway (“FN-RG”) in the first non-3GPP access network.
